}} "'''"You Know What You Are?"'''" is the second track from 2005's ''[[With Teeth (halo)|With Teeth]]''. It is a very aggressive and upbeat song, featuring a gang-shouting chorus and heavy guitar tracks. A remix of this song by [[Clint Mansell]] appeared on the ''Doom'' soundtrack, and played during of end credits of that movie. The title strongly resembles a track on the "[[Head Like A Hole (halo)|Head Like A Hole]]" single, entitled "[[Head Like A Hole (song)|You Know Who You Are]]."
